If I declare the use of xsd:gYear in my ontology, can I use it then? I'm not familiar enough with OWL to answer that question myself, but the way I read ยง9.4 of the OWL syntax [1] I can use any datatype. Can someone more familiar with this topic shed some light on this?

What would an ideal approach look like?
